The Renewable Energy Served to You
A Renewable Energy Mix
26% of CMEC members' power generation needs were provided from renewable sources in 2021.
Since 2012, CMEC has assisted members and contractors through the net metering contract process for over 70 solar sites.

Generating Power from the Sun
Sun Generation
Modern solar generation systems use silicon-based panels to convert sunlight photons into Direct Current (DC) power. This DC power is fed into Alternating Current (AC) inverters that supply your home or business alongside the power grid.

Clearing Up Some Solar Myths
Facts to Clear Up Misleading Sales Statements
1) On-site solar generation does NOT reduce power bills to $0. (Learn more in Q&A, below)
2) On-site solar generation without battery backup will NOT prevent power outages or allow consumers to go off-grid. (Learn more in Q&A, below)

No. AC inverters used with solar installations are designed to cut power to the grid-connected home or business when grid power is lost. This follows international safety standards to prevent "islanding" of the solar site. Islanding could feed high-voltage power back onto the grid power line, endangering the public and utility workers.
Battery backup + solar sites with the correct inverter and anti-islanding controls are available to disconnect grid power and continue serving solar sites. However, these installations come with far higher price tags and limited battery life-expectancies.
For the typical consumer, a properly installed solar generation system will increase debt-payments and possibly insurance premiums, while decreasing electric utility bills. In particular, the energy (kWh) portion of utility power bills will be decreased. Base service availability charges, however, will remain constant on power bills. Demand charges on power bills may or may not be decreased by solar installations.
Service availability charges apply to all power bills, regardless of kWh usage or over-generation. These charges cover part of your cooperative system's infrastructure-upkeep costs to provide continuous power to your home or business. Just like solar panels, grid infrastructure does not last forever.
One insurance company, Nationwide, notes that “certain systems, such as solar panel carports or ground-mounted panels, may require an add-on or separate policy.”
Many times damage to solar arrays is covered under standard home policies, though premiums might need to increase to ensure sufficient coverage for the home and the solar installation in the event of home damage or loss. It is important to check with your insurance agent prior to installing solar. Most members probably desire to have sufficient insurance coverage to protect their structures and any new solar installation investments.
Note that this insurance is generally separate from the liability insurance discussed in Missouri’s Net Metering Law and the Net Metering Contract with your electric cooperative.
CMEC rates were unchanged for four years following April 2018. The April 2022 rate adjustment resulted in a calculated increase of about 0.5% per year for residential members. More importantly, recent industry rate design trends include increasing service availability and demand charges through future years, with sometimes decreasing kWh rates. Such rate designs tend to promote stability and equity in power bills paid by consumers. However, these trends also increase solar payback times.
Price escalation plays a large role in figuring out whether and when a 20-25 year lifespan solar installation will pay for itself. So, accuracy of annual power bill increase assumptions is very important when evaluating solar.
Missouri's net-metering law allows QUALIFYING member installations to net energy over a billing period. For example, if the member overproduces solar kWh in the middle of sunny days and uses grid kWh during morning and evening hours of the same billing period, the kWh total is netted. The member only pays for the grid power they used minus grid power they overproduced.
If this value is negative (more overgeneration than grid usage), the member's account is credited at a kWh rate equal to the avoided cost of power to the cooperative. That rate is usually around $0.02 per kWh (20-30% of retail). This avoided cost is banked to the member's account and may be used to pay for kWh in the member's higher-usage / lower generation months through the next year. Any credits not used within 12 months expire in accordance with Missouri's Net Metering and Easy Connection Act.
